Hull's in California

I'm researching the family on my father’s side of the family. Apprently I've lost a great Aunt and her children. My father and his mother never spoke of them. The known data follows:

Margaret Adams b. 1889, in California. married in the early 1900's to an unknown HULL, divorced (I'm guessing the marriage lasted for the duration of about 1908 to 1914) and living with her daughters Margarita (8 yrs.) and Verginia (10 yrs.)in Burkeley, CA, according to the 1920 Census. According to the census the girls' father was born in "California".

In 1953 I find Margaret living in California, and apprently still living at 2117 McKinley Avenue in Berkeley, Alameda County. This appears to be her parents house as it appears to be the address noted in the 1920 Census.

Questions are: Have I provided any information that helps anyone else? Does anybody have any information to share?
